This thread has been very entertaining. It's one of the few where I saw it start to blow up at the beginning, and couldn't stop. I actually read every post until this one, and Wow!
I have to say... in a world that unfortunately is constantly striving for polarization, only black or white, the world of gray has disappeared. This thread is a perfect example. There is a ton of gray being ignored. I see two sides that are either too strict, or too entitled. I'm really a play by the rules kind of guy. With that said, I also feel kindness and understanding is in short supply these days. Let me give two scenarios which I'd argue opposite sides and side with different parties from above.
@NelleBelle provided the perfect scenario of a medical issue. Maybe not even an emergency, but a medical issue that needs to be addressed. If she did just as she said, excusing herself from the line and walked past me, I'd imagine I'd see her making her way back in roughly 15 or 20 mins approximately. If that happens, no sweat and I'd even joke with her as she passed. "
HEY! No cutting, Red!"
The key is, it's one person (or one with a child or someone in need), she was kind, and she returned after a brief time. Totally cool. I'd defend a person in that instance if they ran into a vigilante who refused to let her rejoin her family.
On the other hand if anyone comes up through the line who I KNOW did not pass me on the way out, and I've been standing in line for at least 30 mins, I'm gonna ask them how their lunch was as they pass by, and see what the reaction is. Their reaction will be very telling if they're lying. Would I start something physical, not likely. It depends on how kind they were as they asked to pass. If they shove me aside, there's gonna be a problem. If you're rude, you can expect it in return. If somebody is alone and apologetic, it won't be an issue because their excuse is more believable. Some individuals above are stating how they're gonna force their way back through the line whether I like it or not. THAT WON'T FLY! Be kind and apologetic, and I probably won't even question it. Be a jerk, we're gonna have problems. If you were in line, and you leave it, it's wise to be polite and apologetic upon your return... period. You'll encounter fewer people who will confront you.
The thing that is NEVER acceptable is a group trying to pass through the line to "rejoin their group". I don't care if it's adults, teens, or an adult with 5 kids. That's a problem if I didn't see you make your way out of line in the last 30 mins, and you would notice an adult leaving the line with a group of kids because they all had to go. In any case, when it's a group that's a surefire sign of one person getting in line while the rest eat lunch, or go on a ride with a shorter line. That's not acceptable. If I see you leave the line and you return shortly after, no sweat. If you're gone a long time, or if I never saw you leave the line and I've been waiting longer than 30 mins, you're gonna be questioned.
One last point, those who insist on forcing their way back no matter what anyone thinks... you are a lot of what's wrong with the world today. That's not showing the kindness and understanding that you claim others aren't showing. People these days don't care about the other person's situation or their effect on others anymore. This country is in a very sad state because of it.
